PROFILE CUTTER-HEAD.

b all @07m/m, it may concern Be it known that we, FRANKLIN L. LANE andHARRISON J. h/.lrrci-IELL, citizens of the United States, residing atBeloit, in the county of Rock and State of Visconsin, have inventedcertain new and useful Improvements in Profile Cutter-Heads, of whichthe following is a specification.

Our invention relates to cutter heads and more particularly profilecutter heads adapted for the nutnufacture of matched or drop siding andcomprising a pair of companion tool-holding plates or flanges havingrelative movement axially of the spindle or arbor whereby to clamp thetools in adjusted operative relation.

The principal objects of the invention are the provision of means forself-centering the head upon the arbor, and means for quicklypositioning and firmly holding cutting bits or tools in the head.

Other features of novelty and improvement will be made apparent from thefollowing detailed description of a preferred embodiment of theinvention, which should be taken in connection with the accompanyingdrawings forming a part of this specification and wherein like referencecharacters refer to the same parts throughout.

In these drawings, Figure 1, is a perspective view showing the improvedplaner head, arbor and tools assembled in operative relation; and Fig.2, is a longitudinal section through the planer head and tools.

The spindle or arbor carrying the planer head is designated by thereference numeral 11 which is provided with one or more longitudinalgrooves 12. The planer head comprises a sleeve 13 having its two endsconed at l-l and split as indicated at 15 so as to render the sameexpansible within certain limits. Extending from the periphery of thesleeve and preferably near one end thereof is a flanged plate 16 whichis fixed with relation to the sleeve 1.3 and may be advantageouslyformed integral therewith. This plate 16 may have an overhanging outerface 17 and is inout upon its inner face at 18 to form one-half of adove tail groove for the reception and engagement of the bits or tools19, the edges of which are beveled as indicated at 20, 20. The plateiange 16 is also provided at spaced intervals concentrically of thearbor and just Specification of Letters Patent.

within its incut periphery with apertures 21. A second plate 22 ismovably mounted upon the sleeve 13 in opposition to the fixed plate 1Gand has its inner face incut at 23 and apertnred at 24.- to correspondto the plate 16. 'When the bits or tools 10 are positioned between theplates 16 and 22 with their beveled edges 20 within and engaged by theincuts 18 and 23 with their cutting edges 25 in proper adjustment toperform the work required,` bolts Q6 are inserted within the registeringapertures 21 and 241 with their heads 27 preferably countersnnk in theoverhanging face 17 of the plate 16 and nuts 28 threaded upon said boltsserve to draw the two plates toward each other and clamp the tools 25firmly therebetween in adjusted relation.

In order to secure the head rigidly upon the arbor 11 clamping rings Q0and 8O which are inwardly coned at 20 and 30a are disposed upon theopposite coned ends of thc sleeve 13. The clamping ring 30 is providedat spaced concentric intervals with apertures 31 into which are threadedthe ends of screw bolts 3Q. These bolts extend through registeringIapertures 33 and 34 of the plates 16 and 22 respectively. The plate 29is provided with correspondingly spaced apertures 35 through which thebolts 82 cxtcnd and. have threaded upon their outer ends the nuts 35. Itwill be seen that by the tightening of thc nuts 35 the two clampingrings 29 and 3() are drawn toward each other and caused to ride upwardlyon the coned split ends of the sleeve 13 whereby the latter are forcedinwardly into intimate gripping contact with the arbor 11.

In order to further insure against angular movement of the head withreference to the arbor, dowel pins 36 are mounted in the sleeve andproject radially into the groove 12 of the arbor whereby to lock the twoelements positively against such angular displacement.

Although we have described herein in detail various structural featuresand characteristics which we have found to bc advantageous, it ,is to benoted that the invention is not limited to these constructiomll detailssince many minor mechanical changes can be made in the device withoutdeparting from the substance and essence of the invention.

We claim:

l. In mechanism of the character described, the combination, With thearbor, of a sleeve having coned ends, a iXed plate carried by the sleeveand having its inner face provided with tool engaging means, said platealso provided with spaced apertures, a second plate movablymounted onthe sleeve in opposition to the first plate, and apertured to correspondthereto, said second plate also having its inner face provided vvithtool engaglngmeans, bolts disposed Within the apertures and bearing onthe outer faces of the plates to clamp the same upon the tools,interiorly coned clamping rings mounted one on each end of the sleeve,and means interlocking with the second plate to draw the clamping ringstogether to clamp the sleeve upon the arbor, substan* tially asdescribed.

2.111 mechanism of the character described, the combination of a sleevehaving sleeve, and bolts interlocked with the plates and disposed Withinthe apertures of the clamping rings to dravv the same together andVclamp the ends of the sleeve upon the arbor, substantially as described.

3. In mechanism oi' the character described, the combination of a sleeveadapted to it upon an arbor andhaving coned split ends, a fixed plateflange formed near one Vend of the sleeve and having its inner faceincut near the periphery and also provided lWith bolt apertures, thesecondY plate slidthe clamping rings together and contract the splitends of the sleeve, substantially as described.
